No. I mean it's impossible for you, Warp, to choose a value from an infinite 
set of values, in *exactly* the same way it's impossible to have an infinite 
number of monkeys typing Shakespeare. Your brain is physically incapable of 
picking any one of those values with equal probability because there are 
infinite numbers of choices which you are capable of expressing or thinking 
about, due to being finite yourself.

Hence, when you pick "0.5", you haven't picked it from the infinite number 
of choices available, but from the finite subset you have ever in y our life 
ever happened to think about beforehand.

Not exactly, no. The axiom of choice says that if you have a set of infinite 
cardinality where each element is a set of infinite cardinality, it's 
possible to create an infinite set by picking one element of each of the 
subsets.
